Saint Patrick’s Day has come to be associated with everything Irish: anything green and gold, shamrocks and “luck.” To those who celebrate its intended meaning, Saint Patrick’s Day is a traditional day for spiritual renewal and offering prayers for missionaries worldwide. Of the many symbols we associate with this holiday, most notable is likely the Shamrock, which happens to be the National Flower of Ireland. Saint Patrick used the three leaves of the Shamrock to explain the Holy Trinity to pagans and unbelievers.
